Vitamin D3 supports hormone regulation, immune function and healthy cell division, playing a vital role across fertility, pregnancy and beyond.
Female Fertility
It helps regulate the menstrual cycle through its influence on oestrogen and progesterone production. It also plays a role in improving insulin sensitivity and reducing inflammation, two key concerns for women with PCOS or endometriosis.
Male Fertility
Vitamin D status is linked to testosterone levels and semen quality. It supports sperm motility and count, and contributes to the regulation of calcium balance within the male reproductive tract, which is essential for optimal sperm function.
Pregnancy
Vitamin D3 is crucial for foetal skeletal development, calcium absorption and immune regulation. Deficiency in pregnancy is associated with increased risk of complications such as gestational diabetes, pre-eclampsia and low birth weight.
Postnatal
Postpartum, vitamin D supports maternal mood, immune defence and bone health. It is also passed through breast milk to the infant, helping support early immune and skeletal development.
